An abrasive, amorphous precipitated silica is provided that provides excellent abrasive performance, but also has a relatively high degree of transmittance, and an index of refraction that is sufficiently low to allow it to be a component of a transparent toothpaste composition having a relatively high concentration of water. The amorphous precipitated silica composition has a refractive index of less than about 1. 4387, a light transmittance of greater than about 48%; and a Brass Einlehner abrasion value of greater than about 5 mg loss/100,000 rev. A dentifrice having a haze value of less than about 70 may be prepared using this abrasive, amorphous silica.

Calcium phosphate colorants are provided that comprise calcium phosphate particles, a dye, and aluminum hydroxide and which are resistant to dye migration and suitable for use in food, drugs and cosmetics. The calcium phosphate particles are coated with a dye and the dye is fixed to the particles by the aluminum hydroxide. Also provided is a method for making a calcium phosphate colorant in which aluminum hydroxide is mixed with a calcium phosphate slurry to deposit aluminum hydroxide onto the calcium phosphate particles contained within the slurry.

A transparent dentifrice is provided that has excellent abrasive performance. The dentifrice comprises from about 10 wt % to about 13 wt % water, and an abrasive, low-structure, precipitated silica having: a refractive index of from about 1. 439 to 1. 450, an oil absorption of from about 90 ml/100 g to about 120 ml/100 g, a light transmittance of greater than about 60%; and a Brass Einlehner abrasion value of less than about 5 mg loss/100,000 rev. Additionally the dentifrice has: a haze value of less than about 50; an RDA of about 50 to 200; and a refractive index of from about 1. 439 to 1. 450.

Precipitated silica product having low surface area and enhanced flavor compatibility. The precipitated silica product is especially well-adapted for use in dentifrices containing cetylpyridinium chloride, which do not attach to the low surface area silica product in a meaningful level and thus remain available for antimicrobial action. Processes for making the low surface area silica product are also provided.

Precipitated silica comprising porous silica particles having a cumulative surface area for all pores having diameters greater than 500 Å of less than 8 m/g, as measured by mercury intrusion, and a percentage cetylpyridinium chloride (% CPC) Compatibility of greater than about 55%. The precipitated silica product is especially well-adapted for use in dentifrices containing cetylpyridinium chloride, which do not attach to the low surface area silica product in a meaningful level and thus remain available for antimicrobial action. Processes for making the silica product are also provided.

A substrate having about 0.5 wt % to about 25 wt % gum incorporated upon it is provided that provides the benefit of delayed viscosity when incorporated into a person care composition such as a toothpaste. Also disclosed is a method for forming gum incorporated onto or into a substrate comprising the steps of: providing a substrate; introducing a liquefied solution of gum to the substrate; and optionally drying the gum-treated substrate to form a dried gum-treated substrate. The invention further includes a dentifrice comprising a gum-treated substrate, and one or more ingredients selected from the group consisting of humectants, abrasives, thickening agents, binders, stabilizing agents, antibacterial agents, fluorides, sweeteners, and surfactants.
